Related to hypoxia: hypoxemia, hyperoxia


 (hī-pŏk′sē-ə, hĭ-)
1. Deficiency in the amount of oxygen reaching body tissues.
2. Depletion of dissolved oxygen in aquatic environments to levels that are detrimental or fatal to aerobic organisms, often caused by eutrophication.

hy·pox′ic adj.


(Pathology) deficiency in the amount of oxygen delivered to the body tissues
[C20: from hypo- + oxy-2 +-ia]
hypoxic adj


(haɪˈpɒk si ə)
an abnormal condition of the body in which oxygen intake or use is inadequate.
[1940–45; hyp- + ox(y)-2 + -ia]
hy•pox′ic, adj.

Noun1.hypoxia - oxygen deficiency causing a very strong drive to correct the deficiency
drive - a physiological state corresponding to a strong need or desire
anemic hypoxia - hypoxia resulting from a decreased concentration of hemoglobin
hypoxic hypoxia - hypoxia resulting from defective oxygenation of the blood in the lungs
ischemic hypoxia, stagnant hypoxia - hypoxia resulting from slow peripheral circulation (such as follows congestive cardiac failure)
asphyxia - a condition in which insufficient or no oxygen and carbon dioxide are exchanged on a ventilatory basis; caused by choking or drowning or electric shock or poison gas
altitude sickness - effects (as nosebleed or nausea) of oxygen deficiency in the blood and tissues at high altitudes
anoxia - severe hypoxia; absence of oxygen in inspired gases or in arterial blood or in the tissues
